Anyone knows how to fix this?

[liuyu666-thu]

never mind. Already solved.

[pavanteja295]

Whats the pytorch version you are using ?

[liuyu666-thu]

@pavanteja295 0.4.0

[hhaAndroid]

@quinnliu4real I also encountered the same problem, how can you solve it?

[liuyu666-thu]

@hhaAndroid use this two commands: export CXXFLAGS="-std=c++11" export CFLAGS="-std=c99"
